1.Introduction

BAUDCOM BD-OLT-2000 is a GEPON Optical Line Terminal (OLT) designed with two GEPON port,two Gigabit optical/electrical uplink Interfaces and management port.

By applications with BAUDCOM GEPON Optical Network Units (ONU) series, BAUDCOM BD-OLT-2000 can provide highly effective GEPON solutions and convenient management for Broadband network. BAUDCOM GEPON technology performs high bandwidth up to 1.25Gbps for both upstream and downstream, and up to 20km Long-Distance Coverage between equipment nodes. It is a cost-effective access technology to bring reliable, scalable and flexible network deployment for Triple-play service applications (voip,data,CATV).
The BD-OLT-2000 is an ideal solution for FTTx applications. The OLT can connect 64/128 remote ONU mostly (by 1:32/1:64 splitter),which can minimize the investment cost for carriers. By using the advanced technology in the telecommunication industry, the BD-OLT-2000 will also provide strong functionalities for Ethernet features such as QoS, VLAN, Multicast, DBA (Dynamic Bandwidth Allocation), and Access Control List.

The OLT system combine the advanced industrial design and manufacturing technology by mini designing.It is high reliability, flexible and easy for installation and maintenance. The OLT is ideal for FTTB/FTTP/FTTH access solutions.
